Version 1.0 - January 2025

Copyright (C) 2025 StillHammer
Contact: alexistrouve.pro@gmail.com

================================================================================
1. PREAMBLE
================================================================================

GroveEngine is a modular C++ engine architecture designed for rapid game
development with hot-reload capabilities. This Commercial License allows you
to use GroveEngine in proprietary, closed-source commercial projects under a
fair royalty model.

This license is intended for:
- Independent game developers
- Game studios creating commercial products
- Anyone who wants to keep their game code proprietary

If you prefer to develop open-source games, consider using the GPL v3 license
instead (see LICENSE-GPL).

================================================================================
2. GRANT OF LICENSE
================================================================================

Subject to the terms and conditions of this license, StillHammer grants you a
worldwide, non-exclusive, non-transferable license to:

- Use GroveEngine in unlimited commercial projects
- Modify the engine source code for your own use
- Distribute games built with GroveEngine
- Keep your game code and modifications proprietary
- Use GroveEngine in both released and unreleased projects

This license does NOT grant you the right to:
- Redistribute GroveEngine itself (source or binary)
- Sublicense GroveEngine to third parties
- Transfer this license to another entity
- Remove or modify license headers in GroveEngine source files

================================================================================
3. ROYALTY TERMS
================================================================================

3.1 FREE TIER (€0 - €100,000 gross revenue per project)

GroveEngine is FREE for projects earning up to €100,000 in gross revenue.
- No upfront payment required
- No royalties owed
- Full commercial use permitted
- All engine features included

3.2 ROYALTY TIER (Above €100,000 gross revenue per project)

For projects exceeding €100,000 in gross revenue:
- 1% royalty on gross revenue above €100,000
- Calculated per-project, not per-entity
- Annual reporting and payment

3.3 GROSS REVENUE DEFINITION

"Gross Revenue" means all revenue directly attributable to a project built
with GroveEngine, including but not limited to:
- Game sales (digital and physical)
- In-app purchases and microtransactions
- Subscriptions
- DLC and expansions
- Advertising revenue
- Licensing fees

Gross revenue does NOT include:
- Platform fees (Steam, Epic, App Store, etc.)
- Payment processing fees
- Refunds issued to customers
- Taxes (VAT, sales tax, etc.)

3.4 CALCULATION EXAMPLES

Example 1: Indie game earning €80,000
→ Royalty: €0 (within free tier)

Example 2: Successful game earning €250,000
→ Free tier: €100,000 = €0
→ Royalty tier: €150,000 × 1% = €1,500
→ Total royalty owed: €1,500

Example 3: Hit game earning €1,000,000
→ Free tier: €100,000 = €0
→ Royalty tier: €900,000 × 1% = €9,000
→ Total royalty owed: €9,000

Note: Unreal Engine equivalent (5% above $1M USD) would be ~€47,500 on €1M

COMPARISON: GroveEngine vs. Other Engines
================================================================================

| Engine        | Free Tier      | Royalty Rate | Notes                    |
|---------------|----------------|--------------|--------------------------|
| GroveEngine   | €0 - €100k     | 1% > €100k   | Best for EU indie devs   |
| Unreal Engine | $0 - $1M USD   | 5% > $1M USD | Higher %, higher tier    |
| Unity         | Subscription   | No royalties | Monthly fees required    |
| Godot         | 100% Free      | No royalties | MIT, but less support    |

between €100k - €500k, with lower royalties than major engines.
